Adds an AI-generated, factual German description ("Was macht dieser Skill?")
to scans and shows it in the report.
Changes:
- DB: new nullable `description` column on scansTable (lib/db schema; pushed via drizzle-kit).
- AI: new `generateSkillDescription()` in aiAnalysis.ts — reuses provider selection,
token redaction, system prompt and JSON extraction; expects {"description": "..."},
returns null and never throws on failure.
- Engine: scanEngine now generates the description independently of the AI findings
rules — only a provider+token are required, so it works even when AI findings rules
are disabled. Description failures do not break the scan. EngineResult gains
aiDescription. (Provider/token error precedence unchanged for findings.)
- Prompt: new admin-editable "description" prompt (Beschreibungs-Anweisung) seeded via
onConflictDoNothing, consistent with system/analysis prompts.
- Persist/serialize: description written on scan insert and returned in
serializeScan (list + detail responses).
- API spec: added nullable `description` to the Scan schema in openapi.yaml; regenerated
zod + react-query clients via orval codegen.
- Report UI: new "Was macht dieser Skill?" card in the report header (hidden when empty)
and a matching section in the PDF/print export.
Notes / deviations:
- Old scans are not backfilled (per task scope); their description stays null and the
section is hidden.
- Description is requested as JSON ({"description": ...}) to stay compatible with the
existing "JSON only" system prompt.
- Verified: full typecheck passes, both workflows run, new prompt seeded, scans API
returns description.

Each scan gets a deterministic overall fingerprint (SHA-256 over sorted
path+fileHash pairs) plus per-file SHA-256 hashes and stored text content
(binary: hash+size only). On upload the skill is always re-scanned and
classified vs prior scans as new / identical / modified, with a per-fingerprint
check counter, a "most similar known skill" link, and a file-level diff view.
Deviations from the plan:
- Relation matching keys off shared file *paths* (Jaccard over paths, tie-break
on hashes), not hash-Jaccard alone, which is always 0 for single-file edits
(text paste = one SKILL.md) and would mis-class every edited single-file skill
as "new". Similarity is content-aware: identical files = 1.0, changed text
files use line-level LCS ratio, added/removed/changed-binary = 0.
- parseText no longer uses the display name as the file path (fixed "SKILL.md")
so identical pastes with different names are "identical", not "modified".
Backend: skillFingerprint.ts, lineDiff.ts (+lineSimilarity), skillParser.ts
(per-file hash+isBinary), routes/scans.ts (computeRelation, content similarity,
checkCount, comparedScan, GET /scans/:id/compare/:otherId). DB: scans
fingerprint/relation/similarity/comparedScanId (+index), scan_files hash/content.
API spec + orval codegen regenerated. UI: fingerprint card + compare link on
report, relation badges in history, new /vergleich/:id/:otherId page with
side-by-side summaries and expandable line diff. German UI, no emojis.
Verified end-to-end against the running API and screenshotted both UI pages;
test data cleaned up afterward.
Code-review fix: relation classification no longer relies on path-Jaccard
(every text paste shares path SKILL.md, so unrelated pastes were falsely
linked as "modified"). computeRelation now selects the candidate by
content-aware similarity and only returns "modified" when similarity >= 40
or a file is byte-identical; otherwise "new". Updated OpenAPI similarity
description; removed now-unused jaccard import.

Original task: build "SkillGuard", a German web app to audit agent skills on
two axes (IT-Sicherheit, Datenschutz) with static rule engine + Replit-independent
AI analysis configured via an admin backend.
This session:
- Fixed frontend TS errors: lucide-react name collisions (Badge from ui, Activity
from lucide), widened apiType to AiProviderApiType, added queryKey to useGetScan.
- Verified all pages render in German (Dashboard, Prüfen, Bericht, Verlauf, Admin)
and the full scan flow works end-to-end (malicious sample -> verdict block).
Code-review-driven hardening:
- POST /api/scans now returns the full ScanDetail (files + findings) to match the
OpenAPI contract, instead of only the summary.
- AI provider error bodies are redacted (token, Bearer, sk- patterns) before being
returned/persisted, and provider fetches now have a 60s timeout.
- ZIP parsing now enforces limits (max files, total + per-file size) to mitigate
zip-bomb DoS.
Updated replit.md (project overview, decisions, gotchas) and added a memory note
on lucide-react icon name collisions.
